The VALUE COLLECTION 821748MSC is a smooth flange bolt designed for high-strength fastening applications in mechanical, industrial, and trade assembly work. It features a 1/2-13 UNC thread size with 1 inch of length under the head and is fully threaded along that length. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, this bolt delivers superior tensile strength and corrosion resistance compared to lower-grade fasteners. The integrated smooth flange distributes clamping load across a wider surface area, reducing the need for a separate washer in many applications. A hex drive makes installation straightforward with standard hand or power tools.
This bolt is suited for heavy-duty mechanical assemblies, structural connections, and equipment fabrication where high clamp load and vibration resistance are required. The fully threaded shank allows maximum thread engagement across the full grip length, making it a practical choice for through-bolting thinner materials or assemblies where engagement depth varies. The phosphate and oil finish provides baseline corrosion protection appropriate for indoor and controlled-environment industrial use.
Designed as a standard 1/2-13 UNC smooth flange bolt for use in mechanical assemblies, equipment fabrication, and structural fastening applications requiring Grade 8 alloy steel fasteners conforming to SAE J429.
Installation is performed by qualified mechanics or tradespeople using standard hex sockets or wrenches sized for a 1/2-13 UNC bolt head. Always ensure mating threaded holes or nuts are clean and free of debris before assembly. Apply fastener torque values per the applicable equipment or structural specification for Grade 8 hardware. Minimum order quantity is 50 units per order.
